brew install clojure/tools/clojureWelcome to Clojure!
Check out Learn Clojure, Resources, or Books to learn the language! If you have questions, you can search or ask at the official forum Ask Clojure.
Clojure requires Java. Clojure officially supports Java LTS releases (currently Java 8 and Java 11), but also tries to ensure interim versions work as well. You can use any Java installation, whether it’s a commercial release from Oracle or an open source version based on OpenJDK (like adoptopenjdk).
The Clojure tools require that either the java command is on the path or that the JAVA_HOME environment variable is set.
Clojure provides command line tools that can be used to start a Clojure repl, use Clojure and Java libraries, and start Clojure programs.
Follow these instructions to install the latest release of the clj and clojure tools:
Install the command line tools with brew from the clojure/tools tap:
brew install clojure/tools/clojureIf you’ve already installed this way in the past, you can upgrade to the latest release with:
brew upgrade clojure/tools/clojureTo install with the Linux script installer:
Ensure that the following dependencies are installed: bash, curl, rlwrap, and Java.
Use the linux-install script to download and run the install, which will create the executables /usr/local/bin/clj, /usr/local/bin/clojure, and the directory /usr/local/lib/clojure:
curl -O https://download.clojure.org/install/linux-install-1.10.1.727.sh
chmod +x linux-install-1.10.1.727.sh
sudo ./linux-install-1.10.1.727.shTo install to a custom location (like /opt/infrastructure/clojure), use the option --prefix:
sudo ./linux-install-1.10.1.727.sh --prefix /opt/infrastructure/clojureExtend the MANPATH in /etc/man_dev.conf to include the manual pages:
MANPATH_MAP /opt/infrastructure/clojure/bin /opt/infrastructure/clojure/manThe linux-install script can be removed after installation.
An early release version of clj on Windows is available at clj on Windows. Please provide feedback on Ask Clojure or Clojurians slack in #clj-on-windows.
See the changelog for version history and the Clojure tap for info on installing older versions or newer prereleases instead.
Local build
Most Clojure users use Clojure jars downloaded from the Maven central repository (by the tools above or other Clojure build tools). However, you can also build Clojure from source with necessary dependent jars into a single executable jar (requires Git, Java, and Maven):
git clone https://github.com/clojure/clojure.git
cd clojure
mvn -Plocal -Dmaven.test.skip=true packageThen start the REPL with the local jar (note this will not work with the jars in Maven as they do not include dependencies):
java -jar clojure.jarTry Clojure online
repl.it provides a browser-based Clojure repl for interactive exploration.
